Efeito cr��nico do alongamento est��tico sobre a capacidade funcional de idosas

Durante o processo de envelhecimento ocorrem altera����es morfofisiol��gicas que podem acarretar em dificuldades na realiza����o de atividades da vida di��ria (AVDs), diminuindo conseq��entemente a independ��ncia do idoso e comprometendo sua qualidade de vida. Para atenuar e/ou retardar tais altera����es, diversos autores t��m recomendado a pr��tica regular de atividade f��sica voltada para o desenvolvimento dos componentes de capacidade funcional (CF). Especificamente para a flexibilidade, a realiza����o de exercícios de alongamento tem sido amplamente recomendada pela literatura. De qualquer forma, poucos estudos analisaram o efeito cr��nico do treinamento da flexibilidade em diferentes volumes sobre a CF de idosos. Desta forma, o objetivo desse estudo foi analisar o efeito de 16 semanas de treinamento de flexibilidade, atrav��s de alongamento est��tico, realizado com dois diferentes volumes, sobre a CF de idosas. Participaram deste estudo 23 mulheres (67,4 �� 7,3 anos; 64,9 �� 8,7 kg; 155,1 �� 5,8 cm; 27,5 �� 3,5 kg/m2) divididas em dois grupos: Grupo Treinamento de 30 segundos (GT30, n=15) e Grupo Treinamento de 60 segundos (GT60, n=8). As participantes do GT30 e GT60 foram submetidas ao treinamento de flexibilidade, com dura����o de 16 semanas e freq����ncia de tr��s vezes semanais. Durante cada sess��o de treinamento, as participantes realizaram tr��s s��ries de exercícios de alongamento para os grupos musculares de membros superiores, inferiores e tronco, com intervalo de 30 segundos entre as repeti����es e entre os exercícios. A CF foi avaliada por meio da bateria de testes motores da American Alliance for Health, Physical Education, Recreation and Dance (AAHPERD) tanto no momento pr�� quanto ap��s oito e 16 semanas de treinamento. Para o tratamento dos dados foi utilizada estat��stica descritiva (m��dia e desviopadr��o), test t de Student para amostras independentes... (Resumo completo, clicar acesso eletr��nico abaixo)

Efeito da especificidade do treinamento (de fundistas e culturistas) sobre os indicadores bioqu��micos do estresse obtidos em teste de esfor��o m��ximo em esteira e com pesos

Dezesseis atletas treinados em muscula����o (grupo AN = 7) ou em corridas de longa dist��ncia (AE = 9) foram submetidos a exercícios de m��xima intensidade espec��ficos e inespec��ficos a sua modalidade de treinamento. A influ��ncia da especificidade do treinamento sobre as altera����es promovidas por sess��es agudas de exerc��cio exaustivo nos par��metros hemodin��micos, de dano muscular e de estresse oxidativo foi analisada, e foram comparados os padr��es de resposta aos exercícios entre os dois grupos. Os testes m��ximos consistiram de teste exaustivo em esteira, utilizando protocolo de rampa, e teste com pesos utilizando cargas iniciais de 80% de 1RM, progressivamente reduzidas, at�� a exaust��o, em dois exercícios que abrangeram grupos musculares distintos. Foram realizadas coletas de sangue antes e imediatamente ap��s os exercícios para a determina����o de indicadores de hemoconcentra����o, de les��o muscular, de processo inflamat��rio e determina����o de par��metros hemogasim��tricos. A glicemia se elevou significativamente ap��s os testes somente para o grupo AE. Foram verificados aumentos significativos na acidose devidos a eleva����o das concentra����es de lactato, H+ combinados a redu����o do HCO3-. Foram observadas varia����es significativas nas concentra����es dos ��ons s��dio e pot��ssio. Tamb��m houveram aumentos significativos nas concentra����es de CPK e DHL. Al��m disso, houveram eleva����es das concentra����es plasm��ticas e dos leuc��citos. Dentro dos par��metros analisados, as respostas observadas n��o foram uniformes em compara����o aos dois grupos, e houve varia����o tamb��m interna aos grupos, quando comparados os exercícios espec��ficos aos inespec��ficos. Os resultados apontam que embora seja esperada uma resposta metab��lica caracter��stica ap��s o esfor��o f��sico exaustivo, a especificidade do treinamento �� determinante sobre os processos adaptativos...

Efeito protetor ap��s sess��es de exerc��cio exc��ntrico: compara����o entre membros superiores e inferiores

The objective of the present study was to compare in which part (lower limb or upper limb) the repeated bout effect has the greatest magnitude. Twelve males individuals with no recent (6 months) experience with resisted training participated in this study. The subjects were randomly divided into two groups (legs and arms) and came to the laboratory 5 times. 1st) adaptation to the dynamometer. 2nd) to perform one bout of eccentric exercise (EE) and provide markers such as isometric peak torque (IPT), delayed onset muscle soreness (DOMS) (both collected before and after the bout) and concentration of the creatine kinase (CK) enzyme in the blood (only before the bout). 3rd) 48 after the first bout the same markers were collected again. After 14 days, the methodologies used in the 2nd and 3rd visits to the laboratory were repeated respectively to determine the repeated bout effect. A significant decrease of IPT and a significant increase of CK and DOMS were found immediately after and 48 hours after the first bout of EE for the arms group. The legs group showed a significant increase in CK (48 hours after the EE) and DOMS (immediately after the EE) resulting from the first bout. In the arms group, the second bout did not cause significant increase in CK or DOMS on any of the situations, however, it provoked a decrease in force production immediately after the EE. The legs group showed a significant increase of DOMS immediately after the second bout of EE, which caused no significant increase in CK. The only marker in which the repeated bout effect happened for both groups was CK. No significant difference was found between the protections for both groups. Taking into account the results, it���s been discussed whether there is a relation between the susceptibility to muscle damage and the repeated bout effect, and also...(Complete abstract click electronic access below)

Participaram do estudo, 11 mulheres ativas (Idade = 31,8 ��� 8,04 anos, Massa corporal = 60,5 ��� 6,49 kg e Estatura = 160,7 ��� 4,35cm). Foram realizados antes e ap��s o per��odo de treinamento os seguintes procedimentos: 1) Teste progressivo de Bruce, para a estimativa do consumo m��ximo de oxig��nio (VO2max); 2) Teste de repeti����es m��ximas, para estimar a resist��ncia de for��a (RF) e; 3) Aula coreografada. O treinamento foi realizado em um per��odo de 6 semanas, com frequ��ncia semanal de 2 sess��es. Houve um aumento significante na RF (de 30,4 3,98 para 37,2 6,25) e no VO2max (de 28,2 6,25 para 34,3 6,24 ml/kg/min) ap��s o per��odo de treinamento. Portanto, um per��odo de treinamento composto por aulas coreografadas envolvendo saltos e um alto n��mero de repeti����es proporciona uma melhora na resist��ncia de for��a de membros inferiores e na aptid��o aer��bia e mulheres ativas

Avalia����o preliminar do efeito da Physalis angulata L. sobre a obesidade induzida por dieta hipercal��rica

The obesity has been considered one of the most serious public health problem in the worldwide scale, especially for being one of the main risk factors for many chronic diseases that characterize the metabolic syndrome. In addition to these diseases, obesity also causes dermatoses that affect not only the individual emotions but also cause various cutaneous infections. Thus, overweighting can be an agent that causes many types of stress: psychological, physical and social. In order to improve people���s life quality, several ethnopharmacological studies indicate plant species for the treatment of disorders associated with obesity due to the attraction of this regimen is perceived as safer and more health effective when compared to the treatment performed by traditional anorectic substances. If considered both food intake and also oral treatment with different compounds can promote change in the gene expression, besides an appropriate diet has been maintenance mechanism of body's vital functions. The aim of this work was to develop new standard methods for induced obesity and stress, which stress is induced through physical and psychogenic stressors in Swiss male mice. Also to evaluate the effect of supercritical extract of Physalis angulata L. on the food intake and corporeal weight loss

Efeito do pacing e do exerc��cio pr��vio na performance aer��bia

The aim of this study was to analyze the influence of prior exercise on different intensity distribution strategies (pacing). The study included five male individuals, apparently healthy, aged between 18 and 25 years, and without regular practice of physical activities. The subjects were tested on different days following the protocols on a cycle ergometer: 1) a progressive ramp test, 2) three constant load tests in the intensities of 85%, 90% and 95% IVO2max to exhaustion, and 3) six tests with and without holding a prior exercise intensity of 70% ��� with different strategies for Even-intensity pace, ES (401 �� 70 W), which consists of an exercise at a pace and / or constant intensity from beginning to end; where intensity is initially increased to 10% less than the ES progressively increase to reach 10% above the intensity of ES, and; Fast-start; FS, where there is a reversal in the way of distributing intensity, ie the initial intensity is 10% higher than the value of ES decreased progressively to 10% below that ES. All these tests were performed in random order. The tlim with previous exercise was significantly shorter than without previous exercise at FS condition (p < 0.05). The VO2final obtained at ES condition was similar with (3243 �� 599 ml.min-1) and without (3252 �� 384 ml.min-1) previous aerobic exercise (p > 0.05). However, the VO2final obtained at FS condition was higher with (3291 �� 218 ml.min-1) than without (3097 �� 207 ml.min-1) previous aerobic exercise (p < 0.05). The heart rate was higher at ES condition with than without previous aerobic exercise (p < 0.05). There was no significant difference in this variable for FS condition with and without previous aerobic exercise (p > 0.05). It can be concluded that the results the previous exercise (���70%) achieved lasting 6 minutes followed by 6 minutes of recovery appears to influence / commit ting the conditions during the pacing for this population

Efeito da aPDT na osseointegra����o de implantes em alv��olos contaminados

Objective: The aim of this study is to evaluate by histometric and immunohistochemistry analysis the effects of antimicrobial photodynamic therapy (aPDT) in alveolar prior to placement of mini-implants in animals with or without induced periodontal disease. Material and method: Thirty-two rats were used. Periodontal disease (PD) was induced by ligature in the lower left first molar. After 7 days of PD evolution, it was performed removal of the ligature and extraction of the left lower first molars in all animals. Thus, animals were divided into 2 groups (n=16) according to the treatments in the dental alveolus before immediate implant installation: MD (control) : mechanical debridement (MD), irrigation with 1 ml of saline solution followed by implant installation; aPDT- MD, irrigation with 1 ml of Toluidine Blue-O and low intensity laser (LLLT) and implant installation. Eight animals from each group were euthanized at 15 and 30 days after the installation of mini-implants. Specimens were processed for histologic, immunohistochemical and histometric analysis. The histometric data were processed for statistical analysis (Kruskall-Wallis and Dunn test; p <0.05). Result: In treatment analysis, results indicated that there was a greater BIC in implants installed in uncontaminated alveolus treated with a PDT ( p<0,05) and greater imuno-reactivity to OPG in bone issue treated with aPDT. Conclusion: The aPDT proved to be effective in bone loss control in no contaminated area and it has increased the bone loss and metabolic activity in alveolus irradiated prior to implant installation.

Aspectos físicos e fisiológicos de sementes de Fimbristylis dicothoma relacionados �� germina����o e dorm��ncia

In the seeds of pioneer plants, the application of treatments for breaking dormancy, and selection by colour and size, are strategies for obtaining seeds of less dormancy and better germination performance. The aim of this study was to evaluate the effect of the physical and physiological aspects of seeds of the tall fringe-rush (Fimbristylis dichotoma) on germination and dormancy. To do this, the seeds were submitted to the following treatments in three studies: (i) control, immersion in H2SO4 (98%, 36N) for 1 minute, immersion in KNO3 (1, 2 and 3%) for 15 minutes, seeding on a substrate moistened with KNO3 (0.2%) and exposure for 5 and 10 hours in a forced air circulation oven at 40 and 70 degrees C; (ii) classification of the seeds by colour (light and dark) and application of the following treatments: control, immersion of the seeds in H2SO4 (98%, 36N) for 1 and 2 minutes, immersion in KNO3 (5% and 10%) for 15 and 30 minutes and seeding on a substrate moistened with KNO3 (0.2%); (iii) classification by size (0.60, 0.50 and 0.40 mm) and germination on a substrate moistened with KNO3 (0.2%) or distilled H2O. The seeds were evaluated by germination test, first count and germination speed index. Moistening the substrate with KNO3 (0.2%), and heat treatment at 40 degrees C for 10 hours improve performance in seeds of the tall fringe-rush. Light-coloured seeds do not display dormancy. Medium-sized seeds of the tall fringe-rush show better performance in terms of percentage and speed of germination.
